original application filed May 11, 1920, Serial No. 330,473. Divided andthis application filed April 17, 1922. Serial No. 554,140.

To all 101 20772 may concern.

Be it known that 1, PETER ldAoGnneon, a citizen of the United States,and resident of Pequannoclz, in the county of Morris and State of NewJersey, have invented certain new and useful THIPTOVGiDGHi/S in OutletGuards for Liquid Receptacles, of which the following a specification.

This invention relates to a construction and arrangement of a guard forthe outlet of a liquid receptacle, such as a tire extinguisher of thetype in which an acid is held in av container positioned in the upperpart; of the receptacle and arranged so that when it is desired tooperate the extinguisher the receptacle is inverted, allowing the acidto mix with a salt solution in the receptacle and cause a gas to begenerated, creating a pressure which expels the contents of thereceptacle.

One of the diiiiculties met with in'the use of ordinary devices of thislrind is that when carried on railroad cars, etc., where they aresubjected to a constant jarring movement, the ingredients slop over andthe solution escapes through the outlet, due to the slopping movement.

This application is a division of my application filed May 11, 1920,under Serial No. 380,473, for fire extinguishers, which application isdirected more particularly to the construction and arrangement of theacid container and stopper for use in a fire extinguisher of this type.This application is directed to the novel features of construc tion andarrangement of the device for preventing the escape, due to the sloppingof the liquid, from the receptacle through the outlet.

The novel construction and arrangement of the guard, as herein shown andde scribed as adapted for use in connection with a fire extinguisher ofthe type described, prevents the escape of the liquid, due to theslopping action, when the extinguisher is in its upright or normalinoperative position but permits the discharge of the same when theextinguisher is inverted, to operate the same, through the outlet fromthe receptacle.

In the drawings I have illustrated one embodiment of the inventionapplied to an extinguisher of the type indicated. In these drawings,Fig. 1 is an elevation, partly in section, showing the extinguisher withthe guard positioned over the outlet. Figs. 2, 3 and i are detail viewsof the outlet guard.

The receptacle, which contains the liquid solution, is shown at 1 and isprovided with a removable cap or cover 2, which also forms a handle forthe device, and with. an outlet 3 to which a hose i and nozzle areattached. All of these parts are of the usual construction and need notbe described in detail.

To prevent the solution from entering the outlet 3 and hose 6L when theextinguisher is in the upright position, as shown in Fig. 1, and issubjected to a slopping action, as on railway cars, etc, a guard 5 isattached to the inside of the receptacle 1 over the outlet opening (seeFig. 2). This guard is preferably of circular shape and constructed of athin piece of perforated metal and may be attached to the receptacle 1by soldering or other suitable means. A second guard or shield 6,similar in shape to the guard 5, except that it is not perforated andits upper edge is out off, as indicated at 7, Fig. 3, is attached to theWall of the receptacle 1 by a hinge 8 and spring clips 9 and 10 over andadjacent but spaced from the guard 5 and spaced a short distance fromthe wall of the receptacle 1 to provide an opening for the solution topass through to the outlet 3 when the device is inverted. Thisconstruction is shown in the sectional view, Fig. 2, and in Fig. 3,which is a face view of the guard 6 and its mounting, Fig.

4 being a section of one of the spring clips, taken on the line l i ofFig. 3.

The cut-ofi portion of the guard 6, at its upper edge, as indicated at7, provides a space for inserting a finger to raise or open the guard 6about its hinge 8 to permit access to the perforated guard 5, forcleaning, etc. The hinge construction prevents the guard 6 from droppinginto the receptacle 1 when opened.

The curved construction of the guards presents a convex face whichrenders the same more eflicient and effective in throwing of]? theliquid slopped against the same. The combination of the perforated innerguard 5 and the non-perforated outer guard or shield 6, arranged asdescribed and shown, has been found to be very efl'ective in actualtests.

What I claim is r 1. In a device of the class described, in combinationwith a receptacle having an outlet, means for preventing the contents ofsaid receptacle from entering said outlet when subjected to a sloppingaction, said means comprising a perforated guard fixed in position oversaid outlet and a second guard positioned over and adjacent but spacedfrom said first guard and hinged at one side to permit the same beingopened to provide access to said first guard.

2. In adevice of the class described, in combination with a receptaclehaving an outlet, means for preventing the contents of said receptaclefrom entering said outlet when subjected to a slopping action, saidmeans comprising a perforated guard fixed in position over said out1et,asecond guard positioned over and adjacent but spaced from said firstguard and hinged at one side to provide access to said first guard, saidguards being curved in form presenting parallel convex inwardlyextending sur faces adapted to throw off the liquid when slopped againstthe same and adapted to permit the passage of the contents of saidreceptacle to said outlet when said device is inverted in position.

3. In a device of the class described, in combination with a-receptaclehaving an outlet a perforated guard positioned over said outlet, asecond'guard positioned over and adjacent but spaced from said firstnamed guard and also spaced a short distance from the wall of thereceptacle, permitting passage of the contents of said receptacle wheninverted but preventing the same from passing to the outlet when subjected to a slopping action.

4. A device of the class described and for the purpose specified,comprising a pair of guards curved in form and positioned one over theother, one being fixed in position and perforated and the other spacedtherefrom and hinged in position thereover and non- )QIfOlEltBtl andpresenting a convex surface ezrtending inwardly preventing the sloppingliquid from entering the outlet over which the guards are positioned.
